Standard Propagation Channel Models for MIMO Communication Systems

Table 1

A comparative description of some MIMO channel models.

Models	Suitable environments	Benefits	Limitations
Kronecker	Local scatters only	Mathematically simple	A special case of VCR
Virtual channel representation	Scatters distribute mainly according to predefined angular directions	Capturing the impact of scattering parameters on channel diversity and capacity	Requiring specific scatter distribution or large array
Weichselberger	Versatile environments	The limitations on VCR being lifted	They require clustered antennas at the Tx and Rx.
Rough surface model [122]	Large plane scatters	Theoretically computing the spatial correlation relative to the scattering surface profile and the channel gain and extending to multiuser channel models	Restricted to specific environments and requiring some parameters of the scattering surface
